There's one thing that bugs me. I mean the whole audio truly is the Horde scenario maybe apart from the "Final 1" part ( I mean Garrosh surely wouldn't call Alliance Players Champions.... So could it be that we have a two part scenario like Theramore where the Horde comes first gets the "kill" on Anduin, Alliance comes afterwards retrieves the body and Garrosch shows up to let us live? ( That would mean Final 1 is actually Final 2 which doesn't add up but ok )
I could be wrong though
